USPS module not working

[Ajeh]

What is the weight being shipped?

What are the settings in the Shipping/Packaging?

[catangirl]

The setting are at:

The weight will range from just 1.2bls to at most maybe 10lbs.
I didn't know what Package tare small to medium meant?

Country of Origin United States

I cannot reproduce this error ...

What is the Ship to address?

What version of Zen Cart are you using?

Clean install or an upgrade? If an upgrade, from what version and how?

[catangirl]

zen cart version 1.3.6

not an upgrade

we've tried with several valid addresses, I don't think that is the issue. I've removed the USPS module and then reinstalle and still does nothing.

Have you contacted USPS and made sure that you are on the production server,
